TL;DR: The reattachment method allows for precise barnacle orientation, enabling the use of small surfaces and the potential for automation, and enables down-selection of coatings from combinatorial approaches to manageable levels for definitive field testing.
Abstract: Standard approaches for measuring adhesion strength of fouling organisms use barnacles, tubeworms or oysters settled and grown in the field or laboratory, to a measurable size. These approaches suffer from the vagaries of larval supply, settlement behavior, predation, disturbance and environmental stress. Procedures for reattaching barnacles to experimental surfaces are reported. When procedures are followed, adhesion strength measurements on silicone substrata after 2 weeks are comparable to those obtained using standard methods. Hydrophilic surfaces require reattachment for 2-4 weeks. The adhesion strength of barnacles in reattachment assays was positively correlated to results obtained from field testing a series of experimental polysiloxane fouling-release coatings (r = 0.89). The reattachment method allows for precise barnacle orientation, enabling the use of small surfaces and the potential for automation. The method enables down-selection of coatings from combinatorial approaches to manageable levels for definitive field testing. Reattachment can be used with coatings that combine antifouling and fouling-release technologies.

07 May 2016TL;DR: Using computer vision to automatically detect computer screens in photo lifelogs is investigated, and it is shown that the technique could help manage privacy in the upcoming era of wearable cameras.
Abstract: Low-cost, lightweight wearable cameras let us record (or 'lifelog') our lives from a 'first-person' perspective for purposes ranging from fun to therapy. But they also capture private information that people may not want to be recorded, especially if images are stored in the cloud or visible to other people. For example, recent studies suggest that computer screens may be lifeloggers' single greatest privacy concern, because many people spend a considerable amount of time in front of devices that display private information. In this paper, we investigate using computer vision to automatically detect computer screens in photo lifelogs. We evaluate our approach on an existing in-situ dataset of 36 people who wore cameras for a week, and show that our technique could help manage privacy in the upcoming era of wearable cameras.

TL;DR: The purpose of this feature topic is to update the IEEE Communications Society community on the status and progress in upgrading PSC systems, in regard to both interoperability and the introduction of state-of-the-art systems and protocols.
Abstract: or many years now, land mobile radio (LMR), based on analog voice communications over locally dedicated radio frequencies and transmission facilities, has been the mainstay of public safety agencies: law enforcement, fire, EMS, and other emergency response departments. Although developments such as trunking and computer-aided dispatch have been introduced to improve the performance and capacity of LMR systems, and access to wireless data has been implemented in some jurisdictions, the quality of public safety communication systems has generally lagged behind that of commercial systems. This disparity in performance and the lack of interoperability between emergency response departments were not fully appreciated until recent crises highlighted the importance of coordinated operations on a broad scale and the need for access to critical data in real time. Now, it is widely recognized that upgrading public safety communications (PSC) infrastructure is a high-priority task, and progress has been made toward implementing interoperability standards and increasing system capacity. Because of their outdated state, in many instances, when LMR equipment and systems are replaced, there is an opportunity to \" skip \" several generations of wireless communications developments. However, for the most favorable design, one needs to understand which features and capabilities of current and near future wireless technology are most suitable for operational and other requirements of local and regional public safety agencies. The purpose of this feature topic is to update the IEEE Communications Society community on the status and progress in upgrading PSC systems, in regard to both interoperability and the introduction of state-of-the-art systems and protocols. Contributions for this feature topic were solicited that discuss recent research, development, deployment, application, and business issues related to the use of wireless technologies for local and regional PSC. The topics of interest included, but were not limited to: • Status of initiatives to improve PSC interoperability and performance • Requirements for future public safety wireless systems • Quality of service and security issues involved in using commercial technologies • Potential of wireless technologies to improve PSC systems and operational performance • Architectures and protocols for broadband, wide area, and digital voice and data public safety networks In response to the call for papers, we received numerous papers of interest. To preserve coherence of the issue and broad scope of coverage, we selected six articles that provide an overview of the state of the art and indicate trends in PSC. The first article, by T. …

TL;DR: The development of the HTS DG system is detailed from the initial feasibility study through the successful demonstration onboard the USS HIGGINS, demonstrating its capability to perform in a naval environment.
Abstract: The need for increased magnetic signature control on Navy ships has lead to the development and adoption of a three axis advanced degaussing system. While this system is effective in reducing the ship magnetic signature, it requires significantly more copper cable than the legacy two axis systems. Degaussing only requires DC currents for field manipulation. Since DC applications is where HTS use excels, a feasibility study was conducted in FY04 to determine the benefits of HTS when used in an advanced degaussing system. Results showed reduced system size and weight, while remaining cost neutral. A series of lab based demonstrations were conducted proving out key aspects of an HTS DG system, most notably cooling a long length of flexible cryostat with gaseous helium. This led to an at sea demonstration of a single HTS DG loop aboard the USS Higgins. This was the first HTS system installed on an active combatant, and it made a successful magnetic range run in April 2009 demonstrating its capability to perform in a naval environment. This paper details the development of the HTS DG system from the initial feasibility study through the successful demonstration onboard the USS HIGGINS.
